I travelled from the UK alone to get gastric bypass surgery. I was recommended highly from my hair transplant doctor so trusted in him. This was a good decision. On the first day you have check ups to fully check you are healthy enough for the operation checking your bloods, breathing, heart and also mental state to undertake the surgery. All the nurses at hospital Liv are helpful and polite and would recommend too anybody to consult with Dr Ömer I’m Istanbul as his services all follow up are great! Thank you Dr Ömer and your team for making the process stress free with transfers and translators all included.
Thank you
Jack
